Describe the procedure for preparation 1 normal oxalic acid
Answers
Oxalic acid is a dibasic acid. It is available in a crystalline form as (COOH)2.2H2O
This is used as the primary standard for acids because it can be weighed accurately.
Equivalent weight of Oxalic acid = (Molecular weight / 2)
= (126 / 2
= 63g
63g of oxalic acid is needed to prepare 1000ml of 1 N Oxalic acid solution.
So 6.3g of oxalic acid is needed to prepare 1000ml of 0.1 N Oxalic acid solution.
To prepare standard N/10 Oxalic acid solution 6.3g of Oxalic acid is weighed accurately and is dissolved in 1000ml of distilled water in a beaker.
